Be it known that l, Minron Mnsiiiioin, a citizen of the United States,rresiding at Milford, in the /onty or New vHaven and State ofConnecticut, have invented a new and useful improvement in PenciiSharpeners; and I do hereby declare the following, when taken inconnection with. the accompanying dr wings and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this lapplication,and represent, iny Fig. 1, a sine view of a pencil Sharpener constructedin accordance with myinvention.

This invention relates to improvement in pencil Sharpeners, particularlyte Sharpeners which comprise a conical,,pencil-tip-receiving recessformed with a slot having a blade arranged to enter said s lot, andespeeially to lpencil sharpeners having cutters or this tvpe mounted ina sheet-metal casing. Tire object of this invention is to provide apencil Sharpener of the type Ireferred to, which shallA he enclosed in asheet-metal housing, which will facilitate the ready withdrawal of t iecutter from the housing and perimt the ready replacement of .cutting'bladesand provide an effective pencil sharpener which may be producedat a very low cost for manufacture, and the invention consists in theconstruction as hereinafter described and particularly recited in theclaims.

In carrying outI my invention, I employ a cutter 10 of substantiallyusual form, with a tapered recess 11 for the reception of the end of apencil to be sharpened. This cutter is formed with a longitudinal slot12, and attached to the cutter by a screw 13 is a blade 1&1-, the edgeof which extends into the chamber 11. The inner end of the 'cutter isformed with a tubular bearing 15, and at the outer end with a stud 16.The hearthe cutter and 25, iez. vserial-nio. 11,435.y

ing 15 and studl are mounted in opposite endsofa Ufshaped:bearing-piece, 17, struck. up from'sheet-metal, and iixed teLtheouterendl of` the stud 16. isl a crank 1.9;

walls -and 21, which, with the ends 17r and 18, form a box to Vreceivethe cuttings froma pencil. This box, with its cutter, is mounted in ahousing 22, also formed from a strip of. sheet-metal bent linto U-shape,with the edges 23 turned outward to form flanges -by whichy the housingmay be ysecured to a support. Extending transversely across the.housingv is a Hoor 24 form-- ing a chamber for the reception of thecutting mechanism, ythis housing beingV closed at theloackby a wall 25formed with a clearance-opening 26 for the bearing 15. Preferably, theouter edge of the floor, on opposite sides of the center, will beformed. with lips 27 for the reception of the lower edge ofthefront-wall 18, which may he conveniently liftedk into the lips 27 bymeans of a finger-piece 28'. Instead of interlocking the cuttingmechanism with the housing by means ofthe lipsf27, the linger-piece 28may be formed with a depression 29 to set over a nub 30 struck downwardfrom Ythe floor 24, as shown in F ig. 6 of the drawings, whereby thecutting mechanism will be interlocked with the housing. I, therefore, donot wish to be understood as limiting the invention to 'any particularmeans for securing the cutting mechanism in the housing.

lA pencil Sharpener thus constructed and shown may be produced at verylow cost for manufacture, and the cutting mechanism may be readilyremoved from the housing to empty cuttings and facilitate the removalvand replacement of the cuttingblade.

I claim:

1. A pencil sharpener, comprising a cutter-frame formed fromsheet-metal, and comprising frontY and rear` walls, a conical cuttermounted-in said walls and provided with a crank, a housing for thereception of'said cutter-frame, said housing comprising a floor uponwhich the cutter-frame rests and a rear wall against which thecutter-frame extends, and means for detachably interlocking thecutter-frame with Y the housing.`

2. A pencil Sharpener, comprising a cutter-frame formed fromsheet-metal, and

comprising front and rear Walls, a conical cutter inounted in saidWalls' and provided with a cyank, a housing foi the reception of saidcutter-frame, said housing comprising a idool1 upon which thecutte-ician'ie rests and a rein1 Wall against which the cutier-frameextends, the forward edge of the said Hoor formed with lips with whichvthe lowei1 edge of 'the cutter-frame may engage, whereby thecuttef-fraine is detachably locked in the housing.

8. A pencil Sharpener, comprising a. cutter-frame having a botorn,sides, and ends extending above the sides, a cutter mounted v in saidends and provided with a crankhandle, a housing formed from a4 strip olsheet-metal bent into Unshape and provided With a, floor upon which thecutter-frame rests and a rear Wall, the said Wall hav-- ing,` aclearance opening for one end of the cutter, said frame adapted to beentered into the said housing.

In testimony whereof, I have signed thisspeciication in the presence oftwo subsciib ing' Witnesses.
